Link Popularity
Link Popularity is a measure of the number and quality of the external links that refer to a website. Link Popularity is very important from the point of view of search engine optimization. Most of the search engines will rank the pages on a website high if it has a high Link Popularity. When any website links to yours it is an opportunity for a user to travel from that website to your website. It is important that the link text for links on other websites contain proper keywords for your website. Search engines will increase ranking of your site for the keywords used because of this. One more important point is that few links from popular websites are more beneficial than the many referral links from low popularity websites.
